TI-84 Evo online calculator: what you need to know
For the first time, Texas Instruments offers the 84 as software you can just open in a browser: the TI-84 Evo online calculator at ti84evo.ti.com. It's the exact factory OS of the new Evo handheld — no emulator hack, no ROM file, made by TI itself. Here's how it works, what it costs, and where its limits are.
What you get
- The complete, unmodified Evo OS: same home screen, same menus, same results — including the new Points-of-Interest tracing and the reworked statistics menus.
- Runs in any modern browser on Mac, PC and Chromebook.
- Perfect for screen sharing in class — teachers can demonstrate keystrokes that match exactly what students see on their Evo handhelds.
What it costs
The online calculator is not sold as a standalone consumer product. A 4-year license comes bundled with the Evo handheld. For schools, TI adds volume licensing: 50 free licenses per 10-pack of teacher devices. If you were hoping to simply subscribe for a few dollars a month without buying the hardware — that's not currently an option.
The structural limits
- Browser-only, with sign-in. There is no offline mode, no desktop app, and — importantly — no phone or tablet app.
- Internet required. No connection, no calculator. On flaky school Wi-Fi, that's a real constraint.
- Not for exams. The Evo handheld is approved for PSAT, SAT, ACT, IB and AP — the online version is a teaching and homework tool, not something you can bring to a test.
- The license expires. After the bundled 4 years, continued access depends on whatever renewal TI offers then.
Online calculator vs. native app
If your calculator use happens at a desk, in a classroom that bought Evo hardware, the online calculator is the most faithful option there is — it's literally TI's own software. But if your calculator lives where homework actually happens — on the bus, on the couch, on your phone — a native app is simply the more practical form factor:
| TI-84 Evo online | Native 84-style app | |
|---|---|---|
| Authenticity | Exact factory OS | Re-created 84 keypad & menus |
| Works offline | No | Yes |
| Phone & tablet | No | Yes (iPhone, iPad, Android) |
| Cost | License bundled with Evo handheld | Free tiers or one-time purchases |
| Best context | Classroom demos, schools with Evo fleet | Homework, studying, anywhere |
